An integrated method for coating and drying solar water tanks

Abstract

The invention discloses an enameling and drying integrated method of a solar water heater water tank. The enameling and drying integrated method adopts an enameling and drying integrated device comprising a coiler. The two sides of the coiler are provided with a slurry inlet pipe and a slurry outlet pipe. The slurry inlet pipe and the slurry outlet pipe are sealed by a slurry inlet plug and a slurry outlet plug. The slurry inlet plug and the slurry outlet plug are connected with a tee joint and a multi-way valve correspondingly. The tee joint and the multi-way valve are connected with a compressed air source, a hot air circulating pipeline, a glaze slurry tank, a redundant slurry tank and other components. During enameling, firstly, the coiler is horizontally placed, the compressed air source is opened, and the inside of the coiler reaches a certain pressure value; then, glaze slurry is fed at a certain pressure, and the pressure difference between the glaze slurry on the left side andthe glaze slurry on the right side is kept at a stable value; when the glaze slurry occupies a certain space in the coiler, high-pressure compressed hot air enters a coiler slurry inlet, the glaze slurry in the coiler continues flowing rightwards under the pressure difference between the glaze slurry on the two sides, and the high-pressure hot air dries the enameling part in the coiler; along with complete discharging of the glaze slurry, the compressed hot air continues being fed for drying, and after drying, feeding the compressed hot air is stopped. The enameling and drying integrated method of the solar water heater water tank improves the enameling quality, saves the use amount of the glaze slurry and improves the work efficiency.

Description

technical field [0001] The invention relates to the technical field of enameling for solar water tanks, in particular to an integrated method for enameling and drying of solar water tanks. Background technique [0002] With the progress of today's society, energy conservation and emission reduction have become an important part of today's social development, and the rational and effective use of various clean energy such as solar energy and wind energy has become an important development direction. my country has a vast territory and is very rich in solar energy resources. Therefore, solar water tanks, which are traditional and simple solar energy utilization methods, have been used in vast areas of the country many years ago. The solar water tank can convert sunlight energy into heat energy, thereby heating the water in the gallbladder from low temperature to high temperature, so as to meet people's use of hot water in life and production. [0003] In the existing solar wa...

Problems solved by technology

Due to the need of anti-corrosion, the current solar water tank coils need to be enamelled, so that the glaze slurry is coated on the surface of the coil, and then the glaze slurry is dried, but the shape of the coil is complicated, and the inner surface is easy to be coated unevenly At the same time, after the enamelling is completed, during the moving process of the coil, because the glaze slurry has not yet formed, it is easy to flow on the inner wall surface, resulting in thicker glaze slurry in some places, and thinner glaze slurry in some places, resulting in the problem of uneven thickness
